摘要

Abstract

A study on the curves of the exchange ratioE(%)- pH on the liquid-solid interface of the systems Zn (II) with clay minerals

(Kaolinite

illite and montmorillonite)

Zn (II) with hydrous ferric oxides (amorphous ferric oxide

geothite and hematite)

Zn (II) with hydrous manganese oxide (γ-MnOOH

manganite and δ-MnO2) etc. in seawater resulted in the discovery of new plateau type exchange ratioE(%)-pH curves not yet reported in literature. The two factors that decide the growth

decline and the change of the “plateau type” curve are: (1) the inherent characteristics of systems

which can be explained by the exchange constants (i=1

etc.) of interfacial stepwise ion/coordination particle exchange between liquid and solid; and (2) $$R_4 = \frac{{\left( {the amount of metal ion in solution} \right)}}{{\left( {the amount of solid exchange reagent} \right)}}$$ . The theory of interfacial stepwise ion/coordination particle exchange in seawater was applied to explain the experimental results of the above study and a general formula was derived for the plateau type exchange ratioE(%)-pH curves. The theoretically simulated and calculated curves coincided well with the experimental results. This paper provides new and powerful experimental basis to support the theory of interfacial stepwise ion/coordination particle exchange in seawater.
